Dust control from a developer’s perspective

valvoja_rakennusmestari

Developers often require a high level of dust management from the building contractor. As such, a reasonable and worthy claim may lead to a dispute between the developer and the contractor about what is a "high level". Defining a level is not unambiguous unless there is a commonly agreed process and metrics to evaluate the outcome. In addition, the estimate often comes from dissatisfied users of the building who complain about the dustiness of the surfaces after moving in.

Environmental certificates guide towards better indoor air quality and overall quality of construction

Instead of of finding an agreement, the appropriate level of dust management is determined by the building inspector who uses a stick and carrot method.

To avoid disputes, consider building according to LEED or Breeam or other certification or method aiming for better indoor air quality. Thus you will improve performance across all key metrics, such as energy savings, water efficiency, CO2 emissions reduction - not only improved indoor air quality.

The environmental certifications for construction take good account of moisture management as a quality factor, but builders also need to consider the effects of dust management during construction to the quality of construction and indoor climate.

In order to meet the criteria for a healthy and safe housing or residence, the contractor must control the construction dust during the whole construction project.

Dust control processes bring structure to the whole project

The requirement for the use of source extractors or local exhaust ventilation systems in all projects alone would make the dust management requirements more tangible. The introduction of building certificates like LEED or Breeam into the construction processes would solve many of the dust control problems, and at the same time clear dust management processes have been found to bring structure into the design and implementation of the construction project. When purity issues are duly considered, the construction will be systematically moved from one stage to another.

polynhallintasuunnitelmaBefore the construction begins, the main contractor will prepare a purity plan for the construction and ventilation works on the site to meet the requirements of the selected purity categories. The purity plan takes a stand on the transportation and storage of building materials and on the compartmentation, source extraction and cleaning of premises during work. Above all, the workers must be trained in clean construction and make sure that the cleanliness and maintenance of the site are taken seriously.

When dust is controlled, the working environment on the construction site becomes safer and more comfortable. The future user of the building is also more pleased when living or working in a dust-free building. And there is no dispute between the developer and the contractor or contractor and the user of the building, at least not because of dust.

Dust control is cost savings on the construction site

ajansaastoWorkplaces that have begun to pay attention to purity have even been discouraged at the outset by purity requirements. However, as the work progresses, the benefits of purity have become clear to the various parties on the site. Workplace safety and comfort increase, material loss is reduced, work precision is increased and customer satisfaction is evident. Purity does not even generate additional costs, but rather savings. The right ways of working and attitude will help change.

Indeed, on sites that focus on purity, it has been found that dust control saves costs, as dustiness results in additional work in the form of cleaning, working area preparation and shielding. Dust is also harmful to power tools, so dust control reduces their maintenance and prolongs service life. Thorough dust control is a good way to reduce costs.

Dust control has a cost, but so has neglect

Of course, the cost of dust prevention is costly, but neglect of purity has its price too:

1. Cleaning costs incur with our without dust control, but the cost of cleaning up dust that has spread all over can be much higher than preventing dust from spreading in the first place.  With less dust, there is less cleaning.

2. There is a cost to installing, renting and using the negative pressure units and source extraction equipment as well as for the required heating of the construction site for negative pressure. Yet, damages caused by dust paid to users of the building can be much higher.

3. The compartmentation causes labor and material costs, but without it, the work progresses slower and the life of the equipment is reduced. The costs of respiratory protection are minimal compared to the costs of absenteeism, not to mention serious occupational diseases.

Effectively implemented dust control will significantly save costs compared to poorly executed or completely ignored dust control.
